Changes in the Distribution of Particle Length of F-Actin Transformed from Mg-Polymer

Abstract
The change in the length distribution of F-actin transformed from Mg-polymer was followed in detail. The Poisson-type length distribution changed into an exponential type within 20 min at 45°C, whereas the number-average length (0.4 μm) remained almost constant. By assuming appropriate rate constants, including those for the reverse reactions of F-actin and nuclei formation, the above process was analyzed numerically.
